Introduction Ribosomes are cell organelles in the cytosol. They serve the construction of proteins. The construction of proteins takes place in different stages within the framework of protein biosynthesis. One part of the protein biosynthesis is the translation, the translation takes place at the ribosomes. Here, the mRNA is translated into amino acid chains from … Ribosomes
Types of ribosomes There are two forms of ribsomes: Free ribosomes, which are freely scattered in the cytoplasm Membrane-bound ribosomes of the rough endoplasmic reticulum (=rER) In contrast to the membrane-bound ribosomes of the rER, free ribosomes are scattered throughout the cytoplasm. The task of the free ribosomes is the production of soluble proteins, which … Types of ribosomes | Ribosomes
Introduction The cell nucleus is the largest organelle of eukaryotic cells and is located in the cytoplasm, separated by a double membrane (nuclear envelope). As a carrier of genetic information, the cell nucleus contains the genetic information in the form of chromosomes (DNA strand) and thus plays an essential role in heredity. Most mammalian cells … Functions of the cell nucleus
In biology, the process of transcription involves the replication of a segment of a DNA strand into a messenger RNA strand (mRNA). The mRNA then contains the nucleic base sequence complementary to the fragment of DNA. Subsequent transcription occurs within the nucleus in all eukaryotes, including humans, whereas subsequent translation, the translation of the mRNA … Transcription: Function, Tasks, Role & Diseases
Translation is the final step in the realization of genetic information. Transfer RNA (tRNA) translates strands of messenger RNA (mRNA) into protein sequences in this process. Errors in this translation are also called mutations. What is translation? Translation is the process of converting the genetic code into chains of proteins. During translation, the mRNA is … Translation: Function, Tasks, Role & Diseases
